{# Note: the wiki edit page can be presented according to several modes:

  - "standard" or "side-by-side" edit mode (`sidebyside` is true in
    the second mode) In standard mode, the edit area is on top of the
    preview, in side-by-side mode there are next to each other.

  - "edit" or "edit+preview" mode (`action == 'preview'` is true in
    the second mode) In edit mode, only the textarea is visible, but
    not the preview.  In sidebyside mode, we always have a preview.
    In this category, we also have the "collision mode" (`action ==
    'collision'`), which happens when a concurrent edit has been
    detected.

  - "wiki preview" or "diff preview" (`diff` is true in the second
    mode) When the preview is shown, it can be either an actual
    preview of the rendered wiki text, or it can be a diff view on the
    changes that have been made (a.k.a. "review mode").  In the latter
    case, `changes[0].diffs` contains the data for the diffs, if any.
    See `preview_or_review` below.
